STEAM-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 340,084, dated April 20, 1886. Application filed January 2, 1886. Serial No. 187,413. (No model.)

To all whom it may concern.-

Be it known that I, ERHARD BAUMANN, a citizen ofthe United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented a certain new and useful Improvement in Steam'Gondensers; and I do hereby declare that the following is a full,'clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in steam-condensers in which exhaust-steam is brought in contact with extensive metallic surfaces, and the steam passing through the same condenses on the inner surfaces thereof, and the resulting water is conveyed by a pipe to be again used to supply the steam-boiler.

I attach the condenser to an exlianstpipe of a steam-engine where the condenser is freely exposed to the air, and my object is to effect a partial condensation of the steam without the use of water. I attain the object by the mechanism illustrated in the accompanying drawings, in which Figure l is aside elevation of the condenser with a portion cutaway to exhibit the interior. Fig. 2 is a horizontal section of the same on the line at. Fig. 3 is a horizontal section of the same on the line y.

Like letters designate like parts throughout the several views.

A is a metallic vessel, having an inlet-pipe, G, at the bottom and an outlet-pipe, I, at the top. The end of .the former pipe extends above the bottom to prevent any of the water of condensation from entering therein. The pipe H is connected to the bottom, and its use is to convey the water of condensation. Two

cone-shaped vessels, D and E, are attached to a common bottom having a rim encircling a central orifice, and which bottom is held by the supports J,attached to the sides of the condenser and concentric therewith. The internal vessel, E, is perforated, so that the steam may pass freely between it and vessel D. The pipe F is attached to the bottom of vessel E, and conveys the water of condensation to near the lower head of the condenser, so that the steam cannot come in contact with the water discharged through the same.

B is a circular trough extending entirely around the interior of the condenser, and to its bottom is attached the pipe 0, to convey the water of condensation to a point near thelower head of said condenser. This trough has an inclined surface to readily carry off the Water.

In use the condenser is attached in any suitable manner to the side of a building, the exhaust-pipe is attached to the pipe G, and the operation is thus: The steam fills the interior, the condensation takes place on the walls of the vessel A, the cone-shaped vessels D and E and the trough B, and upper surfaces of the vessel D, and the several pipes O, F, and H convey the water of condensatiomas heretofore specified.

The condenser would be effective without the trough; but as this furnishes an additional surface it is most effective with this part.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a steam-condenser, the external vessel with pipes G and I to convey the steam and pipe H to convey the water of condensation, the cone D, and perforated cone E, attached to a common base with pipe F,and held concentric to said vessel, and the inclined trough attached to said vessel with pipe 0 to carry off the water of condensation, all substantially as shown and described.

2. Asteanrcondenser composed of vessel A with pipes G and Lthe cone D,and perforated cone E, with pipe F,attaehed to a bottom common to both cones and provided with a rim about its central orifice, substantially as set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

ERHARD BAUMANN.
